Description
Technical Field
[0001] This utility model relates to the technical field of wheel hub repair, and in particular to a bracket for automotive wheel hub repair. Background Technology
[0002] Over time, the surface of the wheel rim may become uneven due to wear, which not only affects its appearance but may also lead to abnormal tire wear and even affect driving stability. In this case, the wheel rim needs to be removed for surface repair or refurbishment. Simultaneously, the wheel bearing is a crucial component connecting the wheel and axle; if the bearing is damaged, it can cause abnormal noises or vibrations during wheel rotation. In this situation, the wheel rim needs to be removed and the bearing inspected for damage; if it cannot be repaired, a new bearing must be replaced.
[0003] In the prior art, CN220637619U discloses an automotive wheel hub inspection rack, which includes an inspection rack with a support rod fixedly installed at the center of the top surface of the inspection rack. Two sets of upper slots are symmetrically opened on the inspection rack on both sides of the support rod. The upper slots are arranged to gradually rise from the side away from the support rod towards the support rod. The two sets of upper slots are arranged so that the tire can be manually rolled onto the inspection rack without the need for multiple people to lift or use other equipment to move it, which facilitates the inspection and improves the work efficiency. The support rod is used to position the tire to be inspected, and the clamping block and support are used to clamp and fix the tire to be inspected. The bracket is used to assist the clamping block to slide. The extension and retraction of the cylinder can drive the clamping block at one end to move against the inspection rack. The movement of the clamping block on the inspection rack can fix, clamp or release the tire to be inspected.
[0004] When in use, the wheel hub is mainly fixed by clamping. However, the inspection of some wheel hubs requires the wheel hub to rotate itself in order to detect the working status of the wheel hub during rotation and to observe whether there are any other problems with the wheel hub. This affects the efficiency of testing the wheel hub after inspection. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bracket for automobile wheel hub maintenance, so as to solve the technical problems mentioned in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A bracket for inspecting automobile wheel hubs includes a support frame, a fixed shaft connected to the top center of the support frame, a support ring rotatably connected to the top outer periphery of the fixed shaft, a support column connected to the top of the fixed shaft, and a positioning element provided on the support column.
[0008] The positioning component includes a hollow rod, an outwardly protruding channel, a through hole, an outer support block, and a sliding plate. The hollow rod is fixedly connected to the top of the support column. The outwardly protruding channels are numerous and arranged in a circular array, fixedly connected to the outer periphery of the hollow rod. A through hole is provided at the top of the inner sidewall of each outwardly protruding channel, and the outwardly protruding channel communicates with the hollow rod through the through hole. An outer support block is slidably connected in each outwardly protruding channel, and the outer support block is dynamically sealed in the outwardly protruding channel. A sliding plate is slidably connected to the bottom of the hollow rod, and the sliding plate is dynamically sealed in the hollow rod. A driving component is provided on the top side of the sliding plate.
[0009] In a preferred embodiment, the present invention can be further configured such that: the end of the outer support block away from the hollow rod is arc-shaped, and the arc-shaped end of the outer support block is provided with an anti-slip groove.
[0010] In a preferred embodiment, the present invention can be further configured such that: the driving component includes a driving screw, the driving screw is threadedly connected to the top of the hollow rod, the bottom end of the driving screw is inserted into the hollow rod and fixedly connected to the sliding plate, and an auxiliary component is connected to the outer periphery of the top of the driving screw.
[0011] In a preferred embodiment, the present invention can be further configured such that: the outer support block is hollow, a sliding plate is slidably connected inside the outer support block, the sliding plate is dynamically sealed inside the outer support block, and an adsorption hole is provided at the bottom of the arc end of the outer support block.
[0012] In a preferred embodiment, the present invention can be further configured as follows: the auxiliary component includes a rotating ring, the rotating ring being rotatably connected to the top of the outer periphery of the drive screw, the outer periphery of the rotating ring being connected to a cavity tube in a ring array, an auxiliary rod being slidably connected inside the cavity tube, the end of the auxiliary rod extending to the outside of the cavity tube and being L-shaped, the end of the auxiliary rod extending into the outer support block and connecting to the top side of the slide plate, and the auxiliary rod and the outer support block being dynamically sealed.
[0013] In a preferred embodiment, the present invention can be further configured such that: a number of insert posts are connected to the top side of the rotating ring, and a support ring is rotatably connected to the outer periphery of the support post.
[0014] In summary, this utility model has at least one of the following beneficial technical effects:
[0015] 1. The bracket for inspecting automobile wheel hubs allows the wheel hub to be initially placed on the support ring and rotated during use. It is positioned by a positioning component, allowing for inspection work. After the inspection is completed, the positioning component is released from the wheel hub, and the wheel hub can then be rotated directly for inspection and testing. This facilitates direct rotation and testing after the wheel hub is inspected.
[0016] 2. The bracket for repairing automobile wheel hubs has an outer support block with one end near the inner circumference of the wheel hub's central shaft hole in an arc shape, which allows the arc-shaped side of the outer support block to better fit the inner circumference of the wheel hub's central shaft hole. The anti-slip groove is provided to increase the roughness of the arc-shaped side of the outer support block, thereby increasing the friction between the wheel hub and the outer support block and improving the stability of the wheel hub's fixation.
[0017] 3. The bracket for repairing automobile wheel hubs is equipped with a drive screw that can be manually rotated when the wheel hub is fixed. When the drive screw rotates, it moves upward. The drive screw and the hollow rod are dynamically sealed. Subsequently, the drive screw will drive the sliding plate to move upward, thereby increasing the air pressure in the hollow rod. This allows the gas in the hollow rod to flow through the through hole into the outward convex channel, thereby pushing the outer support block and thus positioning the wheel hub.
[0018] 4. In this type of bracket for automotive wheel hub maintenance, the auxiliary component, when the drive screw rotates upward, will drive the rotating ring to move upward. Subsequently, the rotating ring will drive the cavity tube to move upward, and as the cavity tube moves upward, it will also drive the auxiliary rod to move upward. The auxiliary rod will drive the sliding plate to move upward, thereby creating a negative pressure inside the outer support block and drawing air through the suction hole. After contacting the inner circumference of the wheel hub's shaft hole, it will be adsorbed, thereby achieving the effect of further positioning the wheel hub. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.
[0025] Example:
[0026] Reference Figures 1-3 The present invention discloses a bracket for repairing automobile wheel hubs, including a support frame 1, a fixed shaft 2 connected to the middle of the top side of the support frame 1, a support ring 3 rotatably connected to the outer periphery of the top of the fixed shaft 2, a support column 4 connected to the top of the fixed shaft 2, and a positioning element 5 provided on the support column 4.
[0027] The positioning component 5 includes a hollow rod 6, an outwardly protruding channel 7, a through hole 8, an outer support block 9, and a sliding plate 10. The hollow rod 6 is fixedly connected to the top of the support column 4. The outwardly protruding channels 7 are numerous and arranged in a circular array, fixedly connected to the outer periphery of the hollow rod 6. The top of the inner wall of the outwardly protruding channel 7 is provided with a through hole 8, and the outwardly protruding channel 7 communicates with the hollow rod 6 through the through hole 8. An outer support block 9 is slidably connected in each outwardly protruding channel 7, and the outer support block 9 is dynamically sealed in the outwardly protruding channel 7. A sliding plate 10 is slidably connected to the bottom of the hollow rod 6, and the sliding plate 10 is dynamically sealed in the hollow rod 6. A driving component 11 is provided on the top side of the sliding plate 10.
[0028] In this embodiment, the hub center through hole 8 is fitted onto the hollow rod 6, and then the drive member 11 drives the slide 10 to move upward, so that the internal air is pushed into the outward convex channel 7 through the through hole 8. As the air pressure in the outward convex channel 7 increases, it will push the outer support block 9 to move outward. At this time, as the outer support block 9 moves outward, its end will fit and abut against the inner circumference of the hub center hole, thereby achieving the effect of fixing the hub.
[0029] The outer support block 9 is made of rubber so that it can deform and increase the contact area when supporting the inner circumference of the center hole of the wheel hub, thereby improving the stability of the wheel hub support.
[0030] In a further preferred embodiment of this utility model, such as Figure 2-3 As shown, the end of the outer support block 9 away from the hollow rod 6 is arc-shaped, and the arc end of the outer support block 9 is provided with an anti-slip groove 12.
[0031] In this embodiment, the outer support block 9 is arc-shaped at one end near the inner circumference of the hub's central shaft hole, which allows the arc-shaped side of the outer support block 9 to better fit the inner circumference of the hub's central shaft hole. The anti-slip groove 12 is provided to increase the roughness of the arc-shaped side of the outer support block 9, thereby increasing the friction between the hub and the outer support block 9 and improving the stability of the hub fixation.
[0032] In a further preferred embodiment of this utility model, such as Figure 2-3 As shown, the driving component 11 includes a driving screw 13, which is threaded to the top of the hollow rod 6. The bottom end of the driving screw 13 is inserted into the hollow rod 6 and fixedly connected to the slide plate 10. An auxiliary component 14 is connected to the outer periphery of the top of the driving screw 13.
[0033] In this embodiment, the drive screw 13 can be manually rotated when fixing the wheel hub. When the drive screw 13 rotates, it will move upward. The drive screw 13 and the hollow rod 6 are dynamically sealed. Then the drive screw 13 will drive the slide plate 10 to move upward, thereby increasing the air pressure in the hollow rod 6. This allows the gas in the hollow rod 6 to flow through the through hole 8 into the outward protruding channel 7, thereby pushing the outer support block 9 and positioning the wheel hub.
[0034] In a further preferred embodiment of this utility model, such as Figure 2-3 As shown, the outer support block 9 is hollow, and a sliding plate 15 is slidably connected inside the outer support block 9. The sliding plate 15 is dynamically sealed inside the outer support block 9, and an adsorption hole 16 is provided at the bottom of the arc end of the outer support block 9.
[0035] In this embodiment, the outer support block 9 is hollow and has a sliding plate 15 inside, and an adsorption hole 16 is also provided on the arc side. When the drive screw 13 moves upward, it will also drive the sliding plate 15 to move upward through the auxiliary component 14, so that a negative pressure is gradually formed at the bottom of the outer support block 9 and air is drawn in from the adsorption hole 16. After the outer support block 9 is squeezed, its side wall will deform. Since the outer support block 9 is supported by the sliding plate 15, only the side wall of the outer support block 9 deforms. At this time, the adsorption hole 16 will fit. Then the drive screw 13 continues to move upward, so that the outer support block 9 deforms and the adsorption hole 16 adsorbs the inner side wall of the hub center shaft hole, further improving the stability when the hub is fixed.
[0036] Alternatively, a hard steel plate can be installed on the inner circumferential side wall of the outer support block 9 to prevent the entire outer support block 9 from being squeezed and deformed, which would affect the stability of the wheel hub support.
[0037] In a further preferred embodiment of this utility model, such as Figure 2-3As shown, the auxiliary component 14 includes a rotating ring 17, which is rotatably connected to the top of the outer periphery of the drive screw 13. The outer periphery of the rotating ring 17 is connected to a cavity tube 18 in a ring array. An auxiliary rod 19 is slidably connected inside the cavity tube 18. The end of the auxiliary rod 19 extends to the outside of the cavity tube 18 and is L-shaped. The end of the auxiliary rod 19 extends into the outer support block 9 and is connected to the top side of the slide plate 15. The auxiliary rod 19 and the outer support block 9 are dynamically sealed.
[0038] In this embodiment, when the drive screw 13 rotates upward, it will drive the rotating ring 17 to move upward. Then the rotating ring 17 will drive the cavity tube 18 to move upward. As the cavity tube 18 moves upward, it will also drive the auxiliary rod 19 to move upward. The auxiliary rod 19 will drive the slide plate 15 to move upward, thereby creating a negative pressure inside the outer support block 9 and drawing air through the suction hole 16. After contacting the inner circumference of the wheel hub's shaft hole, it will be adsorbed, thereby achieving the effect of further positioning the wheel hub.
[0039] When the cavity tube 18 moves upward, it is also pulled by the outer support block 9 moving outward, which causes the auxiliary rod 19 to be pulled from inside the cavity tube 18 to the outside, thus avoiding the phenomenon of the auxiliary rod 19 getting stuck inside the cavity tube 18.
[0040] In a further preferred embodiment of this utility model, such as Figure 1 As shown, a number of insert posts 20 are connected to the top side of the rotating ring 17, and a support ring 21 is rotatably connected to the outer periphery of the support post 4.
[0041] In this embodiment, several inserts are provided for insertion into the screw holes corresponding to the wheel hub to limit the wheel hub. The support ring 21 is provided to support the circular side spokes of the wheel hub. When the wheel hub is finished and needs to be rotated for testing to check for other problems, the rotation drive screw 13 moves downward to attract the outer support block 9 to its original position. The ring moves downward and drives the slide plate 15 downward, so that the outer support block 9 releases its attraction to the wheel hub. Then, the wheel hub can be manually rotated. The wheel hub will rotate on the support ring 21 and will also drive the insertion post 20 and the support ring 3 to rotate, thereby checking whether any other problems occur during the rotation of the wheel hub.
[0042] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
